Abstract

Det er beskrevet et apparat for mating av pulverformet råmateriale som for eksempel aluminiumoksyd til en elektrolyse som produserer aluminium. Elektrolysen Innbefatter et anode- og katodeapparat (l, 2) og organ med hvilket pulverformet råmateriale overføres fra en silo (5) eller tilsvarende til et mateapparat (10, 11, 12, 13, 14, 15) med hvilket råmaterialet mates inn i elektrolyttsmelten (23). Mateapparatet innbefatter en boks (15) som kontrollerer matingen av råmateriale, til hvilken boks et materør (14) for råmateriale er forbundet. Mateorganet tllvelebragt med et mateorgan (13) anordnet til å operere inne l boksen 15, forbundet med en stempelstang (11) eller tilsvarende til en vibrator (10), med hvilken det tilveiebringes en hovedsakllg vertikal vibrasjon (V) av mateorganet. Den åpne nedre enden til boksen (15) er plassert i nærheten av overflaten (22) til elektrolyttsmelten (23) over denne, for å kunne operere inne i elektrolyttskorpen (25).An apparatus for feeding powdered raw material such as alumina to an electrolysis producing aluminum is disclosed. The electrolysis includes an anode and cathode apparatus (1,2) and means by which powdered raw material is transferred from a silo (5) or equivalent to a feeder (10, 11, 12, 13, 14, 15) with which the raw material is fed into the electrolyte melt. (23). The feeder includes a box (15) which controls the feed of feedstock to which box a feed tube (14) for feedstock is connected. The feeder means is provided with a feeder (13) arranged to operate within the box 15, connected to a piston rod (11) or similarly to a vibrator (10), with which a substantial vertical vibration (V) of the feeder is provided. The open lower end of the box (15) is located near the surface (22) of the electrolyte melt (23) above it, to operate within the electrolyte crust (25).
